DOOR LATCH.

Application led March 14, `1928. Serial No. 261,593.

The object of my invention is .the provision of a latch, designed moreparticularly for use on heavy swinging doors, and one that is simple inconstruction and reliable in operation, and is susceptible of beingquickly and easily installed with the formation of but a single openingthrough the thickness of one door.

With the foregoing invmind, the invention in all of lits details will befully understood from the following description and claim when the sameare read in connection with the drawings, accompanying and forming partof this specification, in which:

Figure 1 is an elevation showing my novel latch in working position.

Figures 2 and 3 are sections on the lines 2 2 and 3-3, respectively, ofFigure 1.

Similar numerals of reference designate 2O corresponding parts in allfigures.

I show in Figures 1 and 2, two doors 1 and 2 of horizontal swinging typeadapted when closed to rest edge to edge.

'Ihe door 1 is provided at 3 with anopening which extends through itsthickness, and in the said opening are casing sections 4, of appropriatemetal, shaped as shownand arranged end to end, Figures 2 and 3, and.

equipped with escutcheons 5, attached to .opposite sides of the door.

A lifting lever 6 is pivoted at 7 in one casing section Zl, and isprovided with a pendent handle 8.

Alongside the escutcheon 5 of one casing section l is arranged a beveledkeeper 9 having a pendent shank 10 fixed to one side of the door 1.

Fixed to the -corresponding side of the door 2 is a. wear and stop plate11, and movable vertically in opposed relation to said plate 11 is avertically swingable latch lever l2, pivotally connected at 13 to aplate 14, fixed on one side of the door 2. The lever 12 extends abovethe keeper 9 and lifting lever 6, and is provided at its free end with areturn arm 14 of reduced rod-like form in` cross-section, the said arm14; being joined by a bight 15, Figure 2, to the major portion of thelever 12 and being arranged to rest in front of the major portion oflever 12, Figures 1, 2 and 3, and constitute a convenient handle forlifting of the lever 12 by a person at one side of thel doors 1 and 2.Manifestly the lever 12 is lifted by a person at the opposite side ofthe doors 1 and 2 through the medium of the lever'.

In the preferred embodiment of my invention the latch lever 12 isarrangedand adaptedto play in a guide 16 affixed to the side of the door2.

It will be apparent from the foregoing that when the door 2 swings tothe position illustrated relative to door 1, the lever 12 will ride overand seat behind the keeper 9 and thereby securely fasten both doors inclosed position; also, that precedent to opening of the doors 1 and 2the lever l2 may be lifted and disengaged from the keeper 9 either bystress applied to the hand grasp 14 or .by stress applied to the handle8 of lift lever 6, the latter by a person at the opposite side of thedoors, with reference to the latch lever 12.

It will further be appreciated from they foregoing that my novel latchis simple, strong and compact, and is susceptible of quick and easyinstallation, the latter being due in a considerable measure to theemployment of the opposed casing sections 4 inthe opening 3.

Having described my invention, what I claim and desire to secure byLetters Patent, is:

In combination a beveled keeper, means carrying the same and having anopening, a lift lever mounted in the opening of said means and disposedtransversely thereof, a vertically swingable latch lever pivoted at oneend and engageable with the keeper and the lift lever and having a loopvat its free end and a reduced hand-grasp portion constituting arearwardly extending portion of said loop and spaced in front of andopposite the keeper and lift lever, means carryT ing said latch lever;one of said means being movable relative to the other, a stop platecarried by and extending from one of said means to bring up against theside of thev other means, and casing sections arranged` end to end inthe transverse vopening of the first-named means and having outerescutcheons attached to said means', one of said casing sections havingsecuredtherein and carrying the said lift lever.,

' In testimony whereof, I aflix my signature.
